Attacks on vessels in and around the Strait of Hormuz are intensifying in both frequency and severity, with Iranian strikes increasingly targeting ship engine rooms in a tactic that can knock vessels out of service for months and raise fresh risks to the region’s energy flows.
At least 23 incidents involving ships attacked in or near the strait were recorded in the first two weeks of October alone, with at least five of those strikes directly hitting engine rooms, according to tracking of the escalating campaign.
A direct hit to a ship’s engine room can trigger onboard fires and leave the vessel without power or propulsion, often requiring extensive repairs and sidelining the ship for months, a far more disruptive outcome than attacks on other parts of a vessel.
The shift toward more precise, damaging strikes marks an escalation from earlier phases of the conflict and comes as oil and gas shipments through the strait, one of the world's most critical energy corridors, had been climbing back toward prewar levels.
The growing frequency and precision of the attacks is raising fresh concern among shipping operators and energy traders about the reliability of transit through Hormuz, a chokepoint through which a substantial share of the world's seaborne oil and gas trade passes.
With strikes intensifying rather than easing, shipping companies and insurers are likely to face mounting pressure to reassess risk premiums and routing decisions for vessels transiting the strait in the weeks ahead.
